The plot centers around a lone pilot in a spacecraft attempting to protect a transport ship, the CosmoStation Noah, full of planetary refugees from a fleet of intergalactic terrorists known as the Molok Wardrivers. The player's primary goal is to eliminate all enemy fleets before they can surround the stationary CosmoStation Noah. The player may also visit up to eight different planets in search of engine and weapon upgrades for their ship. Players may also seek repairs at up to five space stations in addition to CosmoStation Noah. The player may also visit an asteroid field, and a black hole from which escape is impossible. The game is won if the player defeats the enemy armada and safely returns to base. However, the game is lost if the enemy fleet reaches the CosmoStation Noah, the player enters the black hole, the player's ship runs out of fuel crystals, or if life support fails.
